Hi, Dr. Ron. I was performing maintenance this weekend and noticed there was a bunch of pink bubble algae on the overflow inside edge. It looked just like Valonia except a very pretty pink color. Sorry, forgot to take a picture. I cleaned them off along with some other grunge. I can't find any mention of this in the forums so should I be overly concerned?

Thanks, all. It appears to be the red bubble variety but it still seems rather pink to me. Since it's certainly not a large scale issue, I won't worry. BTW, it doesn't seem to be covered in corraline at all; totally pink. Thanks, though.
